UNITED STATES NORMAN E. HOUSER, OF LOUIS, MISSOURI v SYRINGE Applicationfiled/August 2, 1929. Serial No. 383,040.

The present invention relates to an atomizer or spray, and contemplatesa construction wherein a continuous'luke-warm' or hot sterile medicatedspray may be obtained instantly when desired, the invention residing inthe construction, combination and arrangement of parts as claimed. i

In the drawings forming part of this application like numerals ofreference indicate 1 similar parts in the several views, and

wherein Figure 1 is a side elevation of the device.

Figure 2 is a plan View partly in section showing the heating element.Figure 3 is a sectional view on line of Figure 2.

Figure 4 is a vertical sectional view through the syringev Figure 5 is aplan view thereof partly in section.

Referring to the drawings inldetail, indicates a container-of anysuitable construction adapted to receive a medicinal solution, and whilethe container may be constructed from-any suitable material and vary inde sign it is preferably of the design illus trated and formed of glassThe container 10 is closed at its upper end by means of a cast- 4, ing11 constituting a cover, preferably formed with a depending flange 12,while interposed between the casting and the cover 11 is a suitablegasket 13.. Depending from the flange 12 at diametricallyopposite pointsare supporting arms 14 arranged at opposite sides of the container andhaving their lower ends extended toward each other and connected with asuitable nut 15, which accommodates an adjustable bolt or screw 16 as Aclearly illustrated in Figure '1. This screw J has one end received by arecess formed in the bottom of the container to assist in supporting thelatter between the arms 14. g

p The casting or cover 11 is formed with a thickened portion whichterminates to provide a socket 17 projecting from one side of thecontainer 10 and adapted to receive a heating device indicated generallyat 18, and which has associated therewith a water supply pipe 19. Thethickened portion of the casting is also formed with a vertical bore toreceive the adjacent end of a hollow tube 20 which depends into thecontainer 10 and terminating a slight distance from the bottom thereof,and through which tube the medicinal solution is discharged. Slidablymounted upon the tube 20 is a piston 21 which when moved downwardly intothe container forces the medicinal solution upwardly through the tube 20as will be readily understood. Upon inspection of Figure 5 it will benoted. that the casting is also provided with a lateral bore or passage22 communicating with the tube 20, and also with a horizontally disposedtube 23, while the casting is further formed with a laterally disposedbore 24 communicating with the adjacent end of the heatin g device 18,and also with a tube 25 arranged adjacent and parallel with the tube 23.The corresponding outer extremities of the tubes 23 and25 respectivelyare associated with a mixing device or head 26 in the form of aninjector, having a single outlet 27 communicating with bores 28 leadingfrom the respective tubes as illustrated. A vertical bore 29' is alsoformed in the casting 11, and communicates with the bore 24, toestablish communication between the latter and the container '10, sothat the aqua solution can be utilized to operate the piston 21 in themanner to be presently described.

The upper end of the tube 20 constitutes a valve seat for the valve 30,and the stem of this valve is threaded into the casting as illustratedand operated by a suitable head or nut 31- The valve, of course,controls the amount of the medicina solution allowed to pass through thetube 20 into the outlet tube 23.

As clearly. illustrated in the drawings, the syringe hereinabovedescribed has associated therewith an electrical heating deviceindicated generally at 18. which includes a casing of proper crosssectional contour to be fitted within the socket 17. This socket isformed withfa bayonet slot torcceive the 99 pin orllug 34 carried by theheating device. Arranged beneath the casing 18 of the heat ing device.and preferably forming an integral part thereof is a valve body orcasing 35 with which the water supply pipe 19 is coupled in any suitablemanner. Operating or solution into the heating device. By reawithin thevalve body or casing 35 is a valve 86, the stem of whi h indicated at 37projects out from beyond the body and is formed or provided with alinger enga-gin button 38. Located within the valve body 35 is a springwhich normally maintains the valve 86 seateh and rclry cuts of?communication lz-etw en the v... er supply pipe 19 and the heatingdevice 18 through the bore or port l0. A heating elen'ient of anydesired construction as it l and arranged rated at ell within the ca1.9; 18 of the heatmg device, so

that when water is allowed to pass from the supply pipe 19 into thesyringe, it passes around the heal'i i cleu'ien :1 and is thereby The(321F111 or body portion ilevice generally is provided 'oal end portion42 which sw. ch indicated igi'ire 3 the operattca projects from oneicion 4-2, and so red with the v: e stem 37, that the entire device canbe conveniently handled or manipulated Depending "from He enlarged end'iortion i a tubular extension 414: which eccivcs Lhe u 1 45 for theheating device- I-ly reason of: the construction illustrated and desk isaa rest that the heating device in us or t be quickly and easilyassociated with the syringe or removed theretrom the occasion mayrequire. In praconly necessary to adjust or regulate the valve 30, andby holding the device in one and, press upon the valve stem 37, thereby.f .cQfllilliQ' the valve 36 to allow the aqua solution to pass from thesupply pipe 19 through the heating device and around the heating element41. his aqueous solution is also forced through the bore 22 into thetube 25. owever. a portion of the solution is also directed downwardlythrough the bore 29 into the container 10. thereby depressing the piston91 and forcing a portion of the medicinal solution upwardly through thetube into the tube The passage of the aqua solution through the tube 25and the mixing head 26 also creates a su tion in the tube 9.3 tofacilitate the discharge of the medicinal solution from the container 10will be readily appreciated.

The medicinal solution and the aqua solution are brought together andmined in the head 26 before the mixture is discharged from the ejectorinto the nose, throat other part of the body to be treated. When thedevice is held in o e hand, the arrangement is such. that the owl ch onbe conveniently closed when desired to heat the water flowing throughthe pipe 19, and at the same time the valve stem 37 can be manipulatedby the index finger to regulate the flow of the Water son of theconstruction illustrated and described it is manifest that a continuouslukewarm or hot sterile medicated spray may be readily obtained whenneeded, and by simply regulating the valve the flow of the said solutionwill remain constant until the container 10 is empty.

\Vhile it is believed that from the foregoing description the nature andadvantages of the invention will be readily understood, I desire to haveit known that I do not limit myself to what is herein illustrated anddescribed and that such changes may be resorted. to when desired as fallwithin the scope of what is claimed.
